Sociologists Chloe Bird and Patricia Rieker set out to “explore and explain the complex dynamics between gender and health,” aiming “to enhance and deepen the understanding of the social determinants of population health” (p ix). Their ultimate goal is to reshape the research agenda on differences between men's and women's health (p xi). To accomplish these ambitious goals, they offer “a new way to think about gender and health by recognizing how the choices of individuals, families, communities, and governments can enhance or undermine health” (p 225).
